To all whom it may concern.-

Be it known that LWILLIAM HENRY SMYTH, a citizen of the United States, and a resident of the town of Berkeley, in thecounty of Alameda and State of California, have invented an Improvement in Can-Soldering Machines,

of which the following is a specification.

spective.

My invention relates to the class of machines for soldering the heads or covers on cans. i

It consists,essentially,of feed and discharge runways adapted to marshal cans to and from axial alinement from and into single file in the direction of their diameters, flux and solder applying rolls or disks, and means for rotatin g cans in contact therewith, and solderjoint wipers and finishers for smoothing and removing excess of solder from the joints.

It also consists in the novel constructions and combinations hereinafter fully described and specifically claimed.

The object of my invention is to provide a simple, effective, and rapidly-operating machine for handling and soldering cans upon a large scale.

Referring to the accompanying drawings, Figure 1 is a side elevation of the marshaling devices to and from the solder-applying portion of the machine, which is shown sufficiently for this figure in general outline. Fig. 2 is a plan of the same. Fig. 3 is an enlarged detail of pivoted section of marshaling-tracks in perspective. Fig. 4 is an enlarged detail of trap of marshaling-tracks, shown-in per- Fig. 5 is a sectional elevation on line X X, Fig. 10, of head soldering and fluxing portion of the machine. Fig. 6 is a side elevation of Fig. 5. Fig. 7 is an enlarged detail in section, showing section of solder-pot with solder disk and wiper. Fig. 8 is a detail in perspective of solder disk and wiper. Fig. 9 is a plan of fluxing and head-solderin g portion of the machine, showing portion of the marshaling-tracks. Fig. 10 is a section on line Y Y of Fig. 9. Fig. 11 is an enlarged detail in perspective of track crossing solderpot cover. Fig.12 shows diagrammatic views, numbered 1, II, III, of the successive positions of the feed and can-rotating rolls when receiving,operatin g on, and discharging a can. Fig. 13 is a side elevation of the solder-joint finishing and wiping device. Fig. 14 is a plan and of sufficient size to receive a can.

naled in the track-frame of A view of the same. Fig. 15 is an enlarged sectional elevation of solder-pot, showing the solder-disks floating in the molten solder, also the manner in which they are guided. It is shown as being broken to permit of being drawn on a large scale. Fig. 16 is an end view of; floating solder-disk and a guide for the shaft on which it is secured. This View also shows how the solder is carried up in a wave against the can. Fig. 17 is an enlarged section across part of the solder-pot, showing the mound or wave above the surface of the solder, as cletermined at the edge of the bath, which is formed by the rotation of the solder-disk.

The main runway A is provided with an opening or trap a, extending across its width (Shown clearly in Fig. 4.) This trap communicates with and forms theend of a second runway A, also provided with a similar trap a, which in turn communicates with and forms the end of a third runway A Each successive runway between its opening and the operating device which it feeds is preferably straight in plan and parallel, except where divergence or convergence is necessary to join, with its neighbor, but variously inclined in elevation to permit each successive branch passing from under its parent runway, the series ending on the same level at the operating device to which the end of the combined runway is secured. This combined runway, as shown in Figs. 1 and 2, leads up to and through the device which operates on the cans and is so constructed that the runway A leads into and over the runway A, as shown in Fig. 2 and in enlarged detail in Fig. At the point of junction of these two runways is a pivoted section m the inner end of which is jour- To the pivot of a is secured the counterbalance a Beyond this pivoted section of runway A runway A crosses over and into runway A, and at their point of junction is provided a pivoted section a which is similar to that already described and is represented in Fig. 3. The runway A is straight in plan and of such an incline in elevation that the speed of the can in this runway after being ejected from the soldering-disks is continually accelerated. In the second runway A the speed of the can is retarded, owing to the curved paths of A in plan and its less incline. In the third runway A the retarding effect is still more pronounced,owing to its still greater curvature and less incline, so that when the cans all reach the runway A in single file there is a distance of several feet between them.

The flnxing device, which receives its supply of cans from the combined tracks, consists of a box or receptacle B (shown in Figs. 5 and 9) for the fluxing fluid. In this receptacle is a series of rolls or disks B, secured upon a shaft b, which is loosely journaled on suitable bearings Z), Fig. 9, in this flux pot or receptacle. These disks are arranged in pairs, suitably spaced to engage the tops and bottoms of cans, and are preferably supplied with tires or laggings of wicking or other absorbing material. (Shown at Z1 Fig. 9.) Above these fluxing-disks and in suitable position to engage cans is a series of rotating driving-rolls B ,pro vided with frictional bearing-bands 11 preferably of an elastic nature, and also provided with flanges b (Shown in Figs. 5 and 9.) These flanges b are suitably spaced to register the cans so that the joint of their tops .and bottoms with the body may properly register with the flux-applying disks. These driving-rolls B are secured upon a shaft B journaled in a suitable bearing. Upon one end of this shaft is secured a drivin g-pulley 13*, which is connected by any suitable power connection with a rotating portion of the machine. I have shown for this purpose the pulley B", grooved on its periphery and driven by a round belt b from the main shaft of the soldering device, Fig. 0. This soldering device consists of a solder-pot D, in which a series of solder-appl yin g disks D are immersed. (Shown in Figs. 5, 7, and 10.) These solder-applyin g disks are secured upon a shaft (7, which is borne loosely upon suitable bearings d in the solder-pot. These bearings may be of any suitable description. One form I have illustrated in Fig. 10, which represents the shaft d as being loosely supported upon centers, but I have found in practice that these bearings may be entirely dispensed with and the shaft with its disks allowed to float freely in the solder, being simply re strained by suitable guards from other than vertical motion, thus providing a soft yielding pressure against the can. This is all clearly shown in Figs. 15 and It in which the restraining guards are shown as slotted guides depending from the cover of the pot. The shaft (1, as is shown in the various views, is entirely below the surface of the solder, so that the majorsegments of the disks are consequently below the solder-surface. This arrangement, which is one of the essential features of this invention conserves important ends,which will hereinafter-be described. The

solder-applying disks D are suitably spaced upon their bearing-shaft (Z to engage with the joints of the tops and bottoms of cans, as illustrated in Fig. 10, wherein cans are shown with dotted lines in position to be operated on. In some cases I have found it advisable to limit the amount of solder applied to the cans and to wipe off any excess of solder which may have been so applied, and for this purpose wipers G are provided, Figs. 7, S, and 5. These wipers consist of flat strips notched, as shown in Fig. 8, to embrace the edge of each solder-applying disk. They are secured to a frame G, which is pivoted concentrically with the solder-applying disks. This frame is suitably connected to the driving mechanism to be raised and lowered above and below the surface of the solder. These connections consist, Fig. 7, of the link g, the rockarm g, shaft 9 and lever g which is suitably engaged with driving-cam II to operate during a portion of the revolution of the said cam.

To feed the cams into operative contact with the solder-applyin g disks and discharge the cans when soldered, two parallel series of driving-rolls E are provided. These rolls E are provided with flanges e, suitably spaced to register the cans with reference to the solder-disks. Each series of rolls E is secured upon shafts c e, which are loosely journaled in a rocking frame E. (Shown in Fig. 10 and also in Figs. 5, 6, and 9.) This rocking frame is loosely pivoted or journaled upon the frame 0 at c, the axis of its pivotal motion being the center of the axially-alined cans when in process of being operated upon, Figs. 5 and 6. To rotate these can-driving rolls E, the shafts upon which they are secured are furnished with gears 6 6 which mesh with a driving-gear F, secured upon the drivingshaft F, which is journaled in the frame 0 concentrically with the axis of the rocking frame E. On the outer end of this shaft are provided tight and loose pulleys or other suitable power connections for giving it rotary motion.

The rolls 1*. are provided with soft or elastic coverings (Shown in Figs. 9 and 10.)

The solder-pot,in which the solder-applyin g disks are immersed, is provided with covers D each of which has two slits or openings at, through which the solder-disks extend, Figs. 11 and 10. Each cover is also provided with tracks a and guides a", which together form a continuation and connection of the compound runways to and from the soldering device, Figs. 11, 5, and 10.

To heat the solder-pot and melt the solder, a suitable heating device L is provided, shown herein as gas and air pipes with a perforated burner-pipe, though any other suitable heating device may be employed, Figs. 5 and 10.

To operate the rocking frame, any suitable means may be employed. The one I herein show consists of a pivoted lever H, which is pivotally connected to the frame 0 at 0'. Its other end is engaged with the lower end of a link h, Fig. 10, whose upper end is loosely connected to a crank-pin E Figs. 5 and 2.

To give suitable motion to this rock-arm II, a cam-groove 7t, suitably curved, is provided, which engages with and drives a cam pin or roller 7L2. (Shown in Fig. 10.) The nature of the groove in the cam II is such that a motion is given, through the connections just described, to the rocking frame E and rollers E, so that they assume successively the positions illustrated in the diagrams in Fig. 12,

with suitable time intervals to properly eifect their functions. The cam itself is driven by means of its engagement through the wormteeth on its periphery with the worm J, secured upon the main driving-shaft,

To regulate the feed of the cans, a stop,Figs. 5 and 6, is provided, which consists of aframe I, pivoted to the frame 0 at t'. A rod '5, Fig. 9, which connects the end levers of this frame, is provided with pins or stops i which project upward and normally extend above the surface of the compound runways in the path of the cans. To operate this stop the tappet I, Fig. 9, is provided, secured to the rocking frame E.

Guards or fenders K are provided, partly encircling the rolls E, as clearly shown in Figs. 5 and 9 and diagram 12.

The device for finishing the soldered cans and making the soldered joint a clean and workmanlike job consists of two parallel buffing-rolls M M, preferably of soft textile material. These buffing-rolls M M are placed longitudinally in the discharge-runway A, as shown in Figs. 13 and 14, near the discharge end of the compound runway and are driven by any suitable power connections. I have shown for this purpose a rope belt N, passing around the grooved pulleys m m on the shaft of each buffingroll. This rope maybe driven by any suitable source of power.

The operation of my device is as follows: The cans already having the tops and hottoms applied being deposited, either by hand or by the heading-machine, in the upper extension of the runway A, beyond the trap or opening a, Figs. 1 and 2, in continuous succession or single file, roll down the said runway till each in turn reaches the trap or opening a, into which it falls and is deflected by the curved portion of the runway A to the trap or opening ct, through which it falls into runway A This series of operations proceeds until runway A is filled completely with cans. Then the last which falls into the trap a serves to close this trap and forms a bridge across the opening a, over which the next and each' successive can will pass into the lower portion of runwayA till this in turn is filled to trap a, when the last can will serve as a bridge, as before, and succeeding cans will roll directlydown runwayA, as described with reference to runway A. hen the compound runway or marshaling device is filled, the leading transverse row of cans isin axial alinement.

For convenience of description it will be assumed that the soldering and fluxing devices have not been in operation until the com pound runway is completely filled,though this is not customary in practice. With this assumption in view, and the main shaft now in motion, the following operation will take place: The rotation of the cam H through the engagement of the worm J and the teeth on the periphery of the cam will transmit motion to the arm H, which in turn, through its connecting-link 7t, transmits rocking motion to the pivoted frame E, causing it to assume the position represented in diagram III, Fig. 12. This motion of the rocking frame E brings the tappet 1 into engagement with the frame 1, thereby depressing its stop-pins t and so permitting the cans to roll down the compound runway against the fenders K. (Shown in diagram III, Fig. 12.) Continued motion of the cam causes the rocking frame E to assume the position of diagram I, Fig. 12, which permits the leading transverse line of cans to roll down and upon the soldering disks, their engagement with which is facilitated and insured by the rotation of the rolls E in the direction shown by the arrows in the diagrams, which not only facilitates the ingress of the cans, but also their discharge when soldered. Continued motion of the cam H causes the rocking frame E to assume the position of diagram II, Fig. 12, in which position the solder is applied by means of the disks d the rotation of these disks being effected by the rolls E through the intervention of the cans. Owing to the fact that the disks project but slightly above the soldersurface'and-rotate quite rapidly, the surface of the molten solder in proximity with the disks is raised in a mound or wave by the centrifugal action of the rotating disk to some little height above the general surface of the solder and disks, and it is this wave or mound of molten solder much more than the simple contact of the disks with the can which makes this device so efficient in applying the liquid metal. Otherobjects of immersing the disks so that their shaft axis and major segment are below the surface of the solder are to overcome the several difficulties which are experienced if the disks project more than half their diameter above the so1dernamely, that the disk being largely exposed to the air permits oxidation of the solder on the exposed surface, thereby forming a coating of dross, so preventing wetting of the disk by the molten solder, thus reducingthe efficiency of the disk to carry solder; also, rapid loss of heat takes place from the exposed surface, so that good and smooth work is impossible; and, further, moderately-rapid rotation of a disk projecting above the solder more than half will cause the solder to be thrown off at various tangential angles, so that high speed, which is essential to good and economical work, is impossible. With my invention the axis of the shaft upon which the disks are secured being below the surface and the disks themselves projecting but slightly above the surface the action in all these particulars is 011- tirely different and all these difficulties, which are serious ones, disappear. The disks in my machine when in operation are, in fact, not exposed at all, being, on the contrary, covered by a thick wave of unbroken solder which rolls against the can, and in effect is the same as though the can were dipped below the surface of the solder, with the advantage of putting any limited part of the can so below the surface of the molten solder. This is clearly shown in Figs. 10, 11, 5, 7, 15, 10, and 17. Further motion of the cam II, and the rocking frame E again assumes the position of diagram III, Fig. 12, and the leading row of cans is discharged. During the latter part of the operation of the soldering the bar G, with its wipers G, is raised above the level of the solder by means of its engagement with cam II. This Wipes the solder from the rolls, which in consequence during this portion of their operation simply rotate as hot disks in contact with the soldered joint and operate to sweat the solder into the joint and carry off any excess which may have been applied thereto. The tracks a and guides a on the cover D together with the flanges on the rolls E, assist and facilitate the passage of the cans through the machine and their accurate registering with the solder-disks. l/Vhile this soldering operation is in process and the lines of cans are held back, the fluXing of the cans preparatory to soldering is accomplished in the manner following: The driving-rolls B of the fiuxing device being in rotation by the engagement through the power connection with the main shaft cause the line of cans to rotate by frictional contact with their periphcries and thereby effect the rotation of the fiuXing-disks, which, being immersed in the flux, deposit it on the cans. The application of solder to the cans being completed and they discharged from the soldering device and being so discharged in axial alinement it becomes necessary for further convenient and economical manipulation of the cans to remarshal them into single file. For this purpose the device illustrated in Figs. 1, 2, and 3 is provided, which consists of a compound runway comprising the number of component runways equal to the number of cans the machine is adapted to solder simultaneously. This compound diseharge-runway is similar in many respects to the compound feed-runway, but having a reverse action. The runway A discharges into runway A, and runway A in turn discharges into runway A. lVhen the cans come from the soldering device, the solder remains molten on the cans for some little time, and it is therefore essential that they receive no jars or shocks or be stopped from continual rotation till the solder is set, as this is apt to cause the tops and bottoms to fall off. To effect this purpose, the pivoted counterbalanced sections a and a are provided, which offer no obstruction to cans rolling on the lower runway, and,

further, give an incline for a can to run down from an upper to a lower runway. The end a is normally in the position therein shown, Fig. 3, being held so by the counterbalanceweight a \Vhen a can rolls into the end a the end is borne down thereby to the inclined position, as stated above, but immediately returns to its normal position when the can has passed over it. The cans are now in single file and in suitable position to receive the finishing operation on the soldered joints, which consists of wiping, smoothing, and polishing the joints while the solder is still molten, so as to leave the can in a bright, smooth, and finished condition, and incidentally to remove and save any lumps or excess of solder which may remain on the can. This is accomplished by the parallel bufting-rolls M, Figs. 1-3 and 14, over which the can rolls, thereby receiving a continual wiping and polishing without a stop or delay being made for this purpose in its journey from the solderapplying device. After rolling over this finishing device the can continues on in its runway to be delivered at any suitable dischargeplace.

It is of course evident that this device is not limited in capacity to that shown in the drawings, which has simply been shown for convenience of illustration as capable of operating on three cans simultaneously. The machine can be made of practically any width and consequent capacity. It will further be seen that though on account of the character of this soldering-machine a device for marshaling cans to and from single file from and into axial alinement is absolutely necessary to its practical and proper working the mechanism I employ for this purpose is not solely applicable to the can-head-solderin g machine, but might be used in any place where it is de sirable for any purpose to arrange cans to and from single file from and into axial alinement.
